UK weather maps show heatwave will last 15 days with 23 counties at 35C or more

UK weather maps show heatwave will last 15 days with 23 counties at 35C or more The UK looks set to face heatwave conditions for at least two weeks as weather modelling maps show more than 20 counties could see temperatures of 35C or higher Weather modelling maps suggest the heatwave which has sent temperatures in the UK soaring above 30C once again could last for more than two weeks. The GFS weather model shows maximum possible temperatures could hit 30C or more every day until July 22 - suggesting heatwave conditions will persist for another 15 days at least. Temperatures look likely to surge above 35C on several days between now and July 22. The data shows highs of 36C coming on Friday this week in western parts of England, with most central and southern areas reaching at least 32C. Similar highs could follow on Wednesday next week, according to the GFS model, with 36C again coming in western parts of England. Some parts of Wales and the far south of England could hit 35C. Saturday next week looks likely to bring the most widespread hot weather, with northern parts of England also rising above 30C. Highs of 37C are on the cards in eastern parts of England, potentially making it the hottest day of this heatwave. Temperature anomaly maps for this period show the UK shaded in areas of deep red. This indicates where temperatures are expected to rise well above the seasonal average. The GFS model maps show 23 counties could see temperatures of 35C or more across the 15 days. They are all in England and Wales. UK counties facing 35C or more England - Yorkshire - Lincolnshire - Derbyshire - Leicestershire - Nottinghamshire - Northamptonshire - Cambridgeshire - Norfolk - Shropshire - Staffordshire - Worcestershire - Warwickshire - Gloucestershire - Wiltshire - Oxfordshire - Berkshire - Buckinghamshire - Hampshire - Hertfordshire - Surrey Wales - Montgomeryshire - Radnorshire - Brecknockshire Met Office's latest weather forecast The Met Office says temperatures this week are not expected to rise to the levels we saw during the June heatwave. However, the national weather agency has predicted some sweltering 35C highs. Forecast temperatures for southern parts of the UK include highs of around 32C today, rising to 33C tomorrow and 34C on Thursday - with isolated locations potentially reaching 35C on Friday and Saturday. Met Office Deputy Chief Forecaster Steven Keates said: “Night-time temperatures again will not be as high as what we experienced in June, though some larger urban areas are likely to remain in the high teens overnight, especially later in the week, and there is a chance that a tropical night (where temperatures do not fall below 20C) may be recorded in a few places. “Much of England and Wales will be hot, and the heat will extend to parts of Scotland and Northern Ireland too, though here peak temperatures are more likely to be in the upper 20s. With high UV and high temperatures, people should take the usual precautions with the heat and the sun.”
